simultaneously tossed into the air. The red ball is given an

initial velocity of 96 feet per second, and its height t seconds

after it is tossed is -16t2 + 96t feet. The green ball

is given an initial velocity of 80 feet per second, and its

height t seconds after it is tossed is -16t2 + 80t feet.

a) Find a polynomial D(t) that represents the difference in

the heights of the two balls.

b) How much higher is the red ball 2 seconds after the

balls are tossed?

c) In reality, when does the difference in the heights stop increasing?

**Damon**, Friday, February 27, 2009 at 4:33pmhr height red = 96 t - 16 t^2

hg height green = 80 t -16 t^2

D = 96 t - 80 t = 16 t

b)32 ft

c) when the first one hits the ground.

D = 96 t - 80 t
